IMPROVEMENT lN TWELVE-BELLS STRIKERS FOR CLOCKS.

Specification forming part of Letters Patent No. 222,913, dated December 23, 1879; application filed May 12, 1879.

To all whom it may concern:

Be it known that I, J OHN KENMUIR, of St. Joseph, in the county of Buchanan and State of Missouri, have invented a new and useful Improvement in Twelve- Bells Strikers for Clocks, &c., of which the following is a specification.

Figure l is a front view of a clock to which my improvement has been applied, part being broken away to show the construction. Fig. 2 is a side view of the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved clock designed especially for use in Masonic lodges, which shall be so constructed that it may be made to strike twelve low bells whenever desired, which will strike at no other time, which will never strike any more nor any less than twelve, and which shall have no appearance of being anything more than an ordinary clock.

The invention consists in the combination of the gear-wheel provided with the notches, at equal distances apart, the gear-wheel provided with the pins, the hook-lever, the cord and red, the case and spring, the coiled spring, the hammer, and the bell, with each other, as hereinafter fully described.

A represents the case of a clock. B is the dial. 0 is the clock-works frame, and D are the clock-works, about the construction of which parts there is nothing new.

To the frame-work O is pivoted a large gear-wheel, E, the teeth of which mesh into a pinion attached to the journ al of the wheel F.

The wheel F drives the regulator Gr, and to the opposite parts of its side are attached two pins, f, which strike the handle of the hammer H, and cause the said hammer to strike the bell I.

In a shoulder of the wheel E are formed a number of notches, e, at such a distance apart that the wheel F will be turned through six revolutions, and thus cause the hammer H to strike the bell I twelve tim s while the said wheel E is revolving through the space between any two notches, c.

The wheel E is stopped by the hook of the lever J dropping into one of the notches c, and is started by raising the said hook out of the said notch 0.

While the wheel E is revolving the hook of the lever J rides upon the shoulder of the said wheel E, ready to drop into the next notch c.

To the other end of the lever J is attached the end of a short cord, K, which passes out through a guide hole or tube, L, in the side of the case A, and to its other end is attached the end of a rod, M.

The rod M passes down through a case, N, attached to the side of the case A, and to its lower end is attached a cord, 0, for convenience in operating itto raise the lever J from the notch in the wheel E.

The rod M is supported by a spiral spring, 1, placed upon it within the case N. The lower end of the spring P rests upon the bottom of the case N, and upon its upper end rests a shoulder or collar formed upon or at tached to the said rod M, as shown in Fig. 2. The spring P thus supports the rod M, takes its weight oft the lever J, and keeps it in proper position to be drawn upon to raise the hook ot' the lever J out of the notch ot' the wheel E.

The lever J should be made heavy, weighted, or provided with a spring to hold its hook end down upon the shoulder of the wheel E, so that it may surely drop into the notches e as it reaches them.

The wheel E, when released from the lever J, revolved by a spring, Q, coiled around its shaft.

The inner end of the spring Q, is attached to the shaft of the wheel E, and its outer end is attached to the said wheel.

The device may be connected with the frame and case of a clock, as herein shown and described, or it may be separated from the clock, as may be desired. The former arrangement is preferred, as it is thus entirely concealed and gives no indication of its presence to a casual observer.

Having thus described my invention, I

claim as new and desire to secure by Letters (3., the hammer H, and the hell I, with each Pate11t other, substantially as herein shown and de- The combination of the gear-wheel E, pro- I scribed.
